Ron, the Soundtraxx documentation says the function outputs are only good for 400mA. I'm thinking those couplers would fry it. There's a PS2 coupler currently installed, but I think those are designed to fire at lower (6V) than the Ps1 couplers which can eat track power. I think that's why John is suggesting going to a PS1 coupler. I read elsewhere on this forum that the PS1 couplers can draw more than an amp, and the Ps2 couplers even more than that.
John, can you suggest a small inexpensive relay that I can try? Most of the ones I'm coming up with on Mouser that have 1amp rated contacts are pretty large. Is there a solid state relay that could work, especially since the duty cycle will be so low?
